From: The roles of cell wall invertase inhibitor in regulating chilling tolerance in tomato

Fig. 4

Over-expression INVINH1 in tomato significantly depressed cell wall invertase activity. a RT-PCR analysis revealed INVINH1 expression was increased in the mature leaves of INVINH1 over-expression plants. The actin gene was used as an internal control. b Cell wall invertase (CWIN) activity of transgenic line2 & 21 was reduced significantly in the mature leaves in comparison with wildtype plant (t test p < 0.01). While the activity of cytoplasmic (CIN) and vacuolar invertases (VIN) were not affected. Each value in (b) is mean ± SE of at least three biological replicates. An asterisk indicates a significant difference (t test, **P < 0.01)
